Bench Linear Regulated DC Power Supply, 2 Channel, 30V, 3A, RS232/USB/LAN Interfaces - 

The New PL series achieves an exceptional power density for a linear regulated power supply by offering up to 90 watts from a ¼ rack 3U sized casing. This gives it an unusually small bench footprint taking up less space on a crowded bench. For rack-mount application, up to four units can be mounted into a single slot. Despite its small size and linear regulation, the New PL series generates relatively little heat through the use of an advanced phase controlled preregulator. This gives it significantly higher energy efficiency than conventional linear regulated designs, particularly when supplying lower voltages.
